Introduction

The Quantum Theory group works to develop theoretical and computational tools enabling the design and understanding of advanced materials, developing new quantum functionalities of materials by nanoscale and molecular engineering and translating these functionalities into quantum devices. These devices include new quantum circuits based on graphene and other 2D crystals, low-power and quantum electronics based on electron spin, photonic devices for secure quantum communication, improved solar energy harvesting and sensing at the single atom, electron, photon and spin level. We are particularly interested in designing emerging properties of materials at the many body level - properties of material which cannot be inferred from the properties of its constituents.
